Each sub panel location has three panels. 230V, 120V and DC. We only needed 6 or 8 breakers per location except for one central panel because all the galley devices hotel services pumps etc, wer within six cabel feet of the panel but on opposite sides of bulkheads and above or below the main deck.
The main power busses were run fore and aft inside two 3" PVC conduits. AC in one and DC in the other. These are protected by 400A Class T fuses. A 400 amp fuse protects the main bus cables and indiviidual breakers protect each branch circuit. Since starter circuits are fed from independent battery start current is not an issue. The helm area has its own DC panel for navigation gear. A DC- DC converter handles the step down from 24V to 12V .for those few devices that cannot use 24V. For the few circuits where remote control is desirable I use latching relays. These do not use power except when actually toggling from on to of or vice versa. An added advantage of latching relays is the ease with which you can have multi point control of the same circuit. For example, you can turn on all deck lights from pilot house, exit to cockpit or even by a wireless remote for when you return after dark by dinghy.
